SPECIFICATION forming part of Letters Patent N 0. 662,391, datedNovember 2'7, 1900. Application filed November 16,1899. Serial No. 737.217. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. BROWN, a citizen of the United States,residing at Wedington, in the county of Washington and State ofArkansas, have invented certain new and useful Improvements inInsect-Destroyers, &c.; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled inthe art to which it appertains to make and use thesame.

This invention relates to new and useful improvements inmachines fordestroying insects and burningseeds of noxious weeds; and its object,among other things, is to provide a device of simple and durableconstruction which may be readily operated and easily moved from placeto place.

To this end the invention consists in the novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, in which- Figure 1 is a sideelevation of my improved device. Fig. 2 is a plan view thereof. Fig. 3is a section on line 3 3, Fig. 2.

Referring to the drawings by letters of reference, A is the frame of themachine, formed of any suitable materiaLprefei'ably metal tubing,mounted upon Wheels B, and provided at one end with handles, as A,Mounted upon the frame A, near the handles thereof, is a shaft 0, at oneend of which is secured a small sprocket O and at the opposite end alarge sprocket or hand-wheel C To one of the wheels B is secured asprocket B, which is connected, by means of a chain D, to the smallsprocket O of the shaft 0. The large sprocket C is connected in asimilar manner to a sprocket E, secured to one end of a second shaft E,mounted near the forward end of the frame A, and to which are securedthe blades F of a suitable fan, which are inclosed in a preferablycylindrical casing F, mounted upon the frame A, as shown. Secured to thecasing F, at the forward part thereof, is a flange G, to which is hingeda semicylindrical hood G, provided with an opening 9 in each end, nearthe front edge thereof, which is normally closed by means of a slide,asg.

Secured to the casing,near the bottom thereof,is a downwardly-exten dingshelf or bracket I-I, preferably of imperforate sheet metal and adaptedto support a grate, as I. This grate is shown of box-like form, open atthe sides and top only, and a small pan or receptacle J, of suitablematerial, is supported thereon by means of standards J or in any othersuitable manner.

End walls are provided between the flange G and the bracket H. Betweensaid flange and bracket the casing F is provided with a horizontalopening F having an outwardlyextending flangef at each edge thereof,said opening and its flanges arranged in a plane above the top of thegrate I, but below the pan J.

A plate, as K, is hinged to the lower forward edge of the shelf orbracket H, and its lower edge is adapted to drag normally over theground when the machine is moved from place to place.

Suitable means are also provided for raising and lowering the hood Gwhile the machine is in operation. These means consist of a rodpivotally connected to the hood G at the upper surface thereof andextending rearwardly to a point adjacent to the handles A. It is obviousthat the hood can be readily raised or lowered by pulling or pushing therod L backward or forward.

In operation fuel is placed within the grate I and lighted in anysuitable manner. The hood G is then lowered and the machine pushedforward. It will be obvious that the revolution of the wheels B will becommunicated through the chains D and sprockets B, 0, C and E to the fanF, creating a blast, which will be forced through the opening F into andthrough the coals in the grate I. The air thus heated is guided downward by the hood G and discharged between the lower edge thereof and theforward edge of the shelf II. By raising and lowering the hood thevolume of heated air discharged may be regulated, and by opening theslides g the air can be directed to the sides in increased volume. Itwill be understood that the plate K will prevent the blast from shootingback under the machine. Should it be desirable to operate the blastwhile the machine is stationary, as when burning stumps, &c., the shaft0 may be disconnected from sprocket G and the fan driven by revolvingthe sprocket G by hand.

It will be understood that any of the Wellknown means now used forchanging gear may be employed for regulating the revolution of the fanin this device.

In the foregoing'description I have shown the preferred form ofmyinvention; but Ido not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what. I claim, and desire tosecure by Letters Patent, is

1. Adevioe of the character described comprising a frame, acasing'thereon having horizontal flanges, a fan in said casing, meansfor operating said fan, a bracket secured to one of said flanges andprovided with a shelf and a grate, a swinging hood covering or inclosingsaid grate, and a system of operating-levers for said hood,substantially as set forth.

2. A device of the character described comprising a frame, a casinghaving horizontal flanges, a fan in said casing, means for operatingsaid fan, a bracket secured to one of said flanges, and provided with ashelf, a grate on said shelf, a swinging hood inclosing said grate, andsecured to the upper one of said flanges, a system of levers for saidhood, a guard-plate depending from said shelf, substantially as setforth.

3. The combination of a frame, a casing thereon having horizontalflanges, a fan in said casing, means for operating the fan, a bracketsecured to the lower horizontal flange and provided with ashelf, a grateon the shelf, a guard-plate depending from the shelf, and

a hood mounted on the upper horizontal flange and adapted to extend overthe grate. In testimony whereof I affix my signature in presence of twowitnesses.

BENJAMIN F. BROWN.
